Every male and occasional female (send nu--never mind) has been caught, for so many nefarious things. Puberty often needs a helping hand--wait--I mean to say that there is a solution to secure your dignity from prying ears -- or eyes depending on applied hex code.
Ingredients 1. Arduino Uno (2) 2. PIR Motion Sensor Module 3. Nerf Walkie Talkies (5$US on eBay) 4. IR LED Transmitter 5. IR Receiver (Salvaged) 6. 47 R 7. 2.2K R 8. TIP120 9. 330 R 10. 5V Relay 11. 4001 D (Optional) Adafruit NeoPixel LED Strip, 1Knf C and 47 R
As the motion sensor is activated, the host MCU triggers the high tone pulse (morse code button) to the other walkie talkie which in turn, the alternate MCU analog reads (A0) voltage from the receiving speaker. When elevated beyond a threshold (identified here as 25) the MCU signals the IR to mute the television and optionally display a LED alert.
A note on refinement for alternative applications -- reduce the delay and transmit pulses (on/off) in Morse so as to reproduce data streams for a broader exchange.
Uh hem, adult entertainment industry, uh hem -- this thing. Eh?!
